1Nn1ANA,A CORPORATION or NEW JERSEY DOORLOCK HANDLE I Application led.Tuly 8, 1931. Serial No. 549,392.

rl'his invention relates to a vehicle door lock and has for itsprincipal object the provision of a lock of such character that when thedoor is locked, the lock handle cannot be removed from the door. In twoforms of the invention, when the door is locked the lock A handle may befreely rotated without aifectmanipulate for purpose oftheft Aortrespass.

' vide vehiclev lt is'a further object to provide a lock of thecharacter indicated which willvbeneat and attractive in appearance andto which the usual form of key control may beaplied.

Formerly it has been the practice to'prodoor'locks with a key operatedstop member which prevents the rotation of the lock handle to unlock thedoor. v The lock handle has been retained in its Vposition 1n the doorsolely by means of a removable eS- since the lock handle to manipulatecutcheon plate'screwed to the door. Upon removal 'of the escutcheonplate, it has genshaped instrument such as a In the present inventionhandle cannot be removed .from the door when the door is locked, therewilLbe no possibility of removing the the locking mechanism and in theirst mentioned forms of the invention the handle cannot beforced orbroken of by means of an additional leverage such as a piece 'of pipe,which .is sometimes with a suitably screw driver.

used in attempting to; gain unlawful entry to v a parked vehicle.

In the second form of the invention, the handle may possibly be brokenforces be applied thereto, but

organized that the locking mechanism cannot be manipulated eventhoughthe handlev both -rotational and axial move-v sco e ofthesubjoined claims.

shouldbe broken olf by `the application of such excessive force.

It will therefore be seen that the application ofmy invention willgreatly add to the safety of parked vehicles and will tend to discouragethose intent upon forcing an un the same. l

forth the principalobjects and advantages of my invention, thesame willnow be briefly described in order that others skilled in the art maymake and` use thesame.

Three suitable methods by which my invention may be applied are shown inthe accompanying drawing. This drawing, however, is to be considered asillustrative on y and the invention is to be limited solely by thelawful entry into Having thus set eferring to the accompanying drawing:Figure 1 is alongitudinal sectional view of the preferred form oftheinvention, cer'- tain parts beingubroken away to better illus- .tratethe construction thereof.

Referring to meral 10 indicates the outer in which the lock is mounted.

Figures 1, -5 and 7, the nupanel of the door Numeral `11 indicates theusual lock plate secured at the inner side of the door, numeral 12indicates the edge surface of the door, numeral 13 indicates theweatherbead and numeral 14 the channel for the sliding door, glass. Asthis` construction is usual and well known, a further description is notconsidered necessary for the purpose of this disclosure.

Referring particularly to Figure 1, the numeral 15 generally indicates adoor lock handle, the exterior portion 16l of which is constructed inthe usual manner and'is provided with a handle portion and a well orbore 17 receiving, a lock barrel 18 which is l'adapted to be actuated bya key 19.

Between the' lock handle and vthe door panel 10- there is provided anescutcheon plate 20 of any preferred construction. The handle 15 isprovided with a tubular stem 22 which extends into the door andterminates in a portion 23 provided with a bore 25' which rotatablyreceives an enlarged end 26 of a latch operating member generallyindicated at 27 The portion 23 is beaded over the enlarged end -26 at 28so that the parts 15 and 27 cannot be separated. The latch operatingmember 27 further compris the spindle portion 30 and a squared vendportion 31 receivable in a cam 32 to operate the latch tongue 33.

Between the door panel 10 and the end portion 23, the member 22 isprovided with a transverse slot 35 illustrated in Figure 2. Within theslot 35 there are pivotally mounts ed u on the pin 36 a pair ofrotatable lever-v mem `ers 37 and 38 shown in section in Fig- .ure 2.

Extending from the end of the slot 35 to the inner end of the well 17 isa bore 40. somewhat smaller in diameter .than the well A 17. lWithinthis bore 40 is a rotatable member 41 which is secured to the lockbarrel 18 and is rotatable therewith by meansgof the key 19.y The member41 at its innerend is provided with a pair of oppositely positionedcylindrical extensions 42 and 43 which engage in recesses 45 and 46provided in the members 37 and 38 res ectively.

From the construction just explained, it will be seen that a rotation ofthe member 41 wlll rotate the members 37 and 38 in opposite directionsaboutthe pin 36 to`change thelr position from that illustrated, inFigure 1 to that illustrated in Figure 4, or vice versa. It will befurther observed that end portion 25 of' the member27 is provided with atransverse'slot 47 in which the levers 37 and 38 extend Figure 4 tosecure the members 15 and 27 agalnst relative rotation so that movementof the lock handle 16 will rotate the spindle 27 to operate the latch33. This corresponds to the unlocked condition of the door. When thelever members are extended as in Figure 1, they do not engage the member27 and theA when in the position illustrated in Leaaeea trated in Figure1, they will engage the inner surface of the washer member and therebyprevent removal of the handle 15 from the door.

The portion 26 of the member 27 is also provided with a secondtransverse bore 50, particularly illustrated in Figure 3. Within thisbore are positioned a pair of balls 51 and 52 which are urged away fromeach other by the compression spring 53. The portion 23 of the handlemember 15 which surrounds the portion 26 of the member 27 is providedwith a series of spaced apertures 55, 56, 57

and 58, somewhat smaller `in diameter than the balls 51 and 52.

From an inspection of Figure 3, it will be seen that the balls extendinto these apertures to define certain limiting positions in therotation of the member 15 relative to the member 27, and that one ofthese-positions is such that the lever members 37 and 38 may be freelyrotated into the slot 47.

From an inspection of Figure 2, it will be observed that the levermembers 37 and-38 are each provided with an extension overlapping thethickness of the other lever so fit snugly into the slot that theleverswill 47 and will"prevent the handle member l5 from having anyappreciable amount of lostr motion relative to the latch operatingspindle 27.

In the modification illustrated in Figure 5, the numeral 60 generallytinuous member including the door lock handle and the latch operating'spindle. This member'is provided with a transverse slot 61, an axial.bore 62, and a well 63 .for the lock cylinder 65. Within (the slot 61and pivotally mounted about the pin 66, area pair of rotatable levermembers 67 and 68 the ends of which may lie wholly within the slot asillustrated in Figure 6, or may be extended out of the slot asillustrated in Figure 5. Within the bore 62 is a rotatable member 70operatively connected with the lock cylinder 65at one end provided atits other end with a pair of spaced cylindrical extensions 7l and 72which engage 4in recesses 73 and 74 providedin the members 67 and 68respectively. i

Secured to the inner side of the panel 10 surrounding the member 60 is awasher member 76 which is'provided with oppositely disposed slots 77 and78 in which the ends Vof the lever members 67 and 68 engage whenindicates a conv lever members`67 and 68 in the slots 7,7 and 78 willeffectively prevent rotation of the handle. to unlock the door, and atthe same time will prevent removal of the handle from the door, eventhough the escutcheon plate 80 should. be moval of the handle 81 fromthe door.

In the modification illustrated in Figures 7 and 8, the numeral 81generally indicates a door lock handle provided with a cylindriurgedoutwardly with bore to receive a bears against the lock mechanism` andstrainsfthe spindle 92 from lcylinder 8 cal portion 82 extending intothe door an .terminating in an end portion 83 provided an .internalcylindrical boie 84. The handle member 81 is further provided with awell` 86 in which is tted a lock cylinder 87, a second bore 88 withinwhich is a rotatable cylindrical member 89 and a transverse slot 91between the end portion 83 and the inner end of the bore 88. I v

The numeral 92 generally indicates a lock operating spindle providedwith an enlarge end portion 93 telescopically received in the endportion 83 of the member 82, a shank por-` tion 95, and a squared endportion 96 nonrotatably received in the cam 97 which operates the doorlatch 99. The end portion 96 is further provided with a screw threadedscrew 100, the head of which longitudinal movement.V

It will be observed that the end portion 83' 'of the member 82 ,isbeaded overa shoulder P of the portion 93 of the member 92 at 101 tosecure the members 81 and 92 together so that the screw 100 willeffectively prevent removal of the handle 81 from the door. The portionv93 is provided with a verse bore 103 within which is a ball 104 of thebore. by a compres- The member 83 is provided with an aperture 107somewhat smaller than the ball and intovwhich the ball extends to definea limiting position in the rotation of' the member 81. relative-to themember 92. The portion 93 is also provided with a pair of extensions,one of which is illustrated at 108 which provides between lthem atransverse slot ier the reception of the end vof a levei member 109pivoted in the slot 91 about the pin 111. f

The lever member 109 is provided with a sion spring 105.

recess 112 into which projects 113 formed on the member 89 so thatrotation of the member l89 by the key operated lock will serve to movethe lever 109 from the osition shown in Figure 7 to the position shownin Figure 8 or vice versa.

Mounted between the handle 81 and outside of the door panel 10 is anescutcheon plate generally indicated at 115.

From this description, in this modiiication I have also provided a doorlock in which moved from the door and in which the lianlas follows:
